Vivek Ramaswamy wins the Ohio Republican primary for governor, NBC News projects, defeating businessman Casey Putsch in a contest for the open seat created by term-limited Republican Gov. Mike DeWine. Multiple outlets describe Ramaswamy as the leading contender heading into the primary, including reports that President Donald Trump endorsed him. The Democratic side faces no primary challenge, with Dr. Amy Acton winning the Democratic nomination without opposition, according to NBC News. With both nominations set, the general election matchup is set for November between Ramaswamy and Acton. Coverage across outlets characterizes the general election as potentially competitive, with some noting close polling and the possibility of a high-spending race. While Ohio is often described as unfavorable for Democrats in recent election cycles, several sources emphasize that Acton’s profile as a former state health director could set up a closely watched race. The primary results also position Ramaswamy to compete as the Republican nominee for the governorship in 2026.
